large or flawless, will look dull. A well-cut diamond will sparkle brilliantly, reflecting light in a way that makes it appear even larger and more vibrant.
When a gemologist inspects a diamond, they focus on specific values—depth percentage, table size, crown angles, and symmetry—all of which determine how light moves through the stone. Too shallow, and light leaks out of the bottom. Too deep, and it escapes through the sides.
For round diamonds, look for Excellent or Ideal cuts, as these maximize brilliance. Fancy shapes, like ovals or emerald cuts, have different proportions, so their ideal measurements vary. No matter the shape, a well-cut diamond will always outshine a poorly cut one.

The 4C's: What Really Matters in Your Diamond
Choosing a diamond is more than just picking a carat weight. The 4C's—Cut, Color, Clarity, and Carat—work together to define its beauty and value. Each plays a role, but some matter more than others.
Cut: The Single Most Important Factor in Brilliance
Color：What You See vs. What You Pay For
Color in diamonds isn’t about bold hues—it’s about how white or yellow a diamond appears. The highest color grades, D-F, are completely colorless and the most sought after. But many buyers prefer G-J diamonds because they appear nearly identical to the untrained eye yet cost significantly less.
One overlooked factor? Fluorescence. Diamonds with medium to strong fluorescence may look whiter than their grade suggests, especially in natural sunlight. A well-chosen H or I color diamond with fluorescence can look as bright as a D-F diamond while costing much less.

Clarity: What You Can and Can't See
Clarity measures how many internal or external imperfections (inclusions and blemishes) exist inside a diamond. The fewer, the better—

Understanding Diamond Carat Weight
A diamond's carat weight is determined by its size, with larger diamonds weighing more. However, it's important to note that carat weight is not the same as size, as other factors such as depth and shape can also impact how large a diamond appears.
